quently hold in the mouth immediately L Box.

Application led June 16, 1925. Serial N0. $7,507.

My invention relates to boxes and particular .boxes made from a singlesheet of aperor liber-board.

ne of the objects of the invention is the provision of a boxforpackaging heavy products, such as nails, in such a manner that theintegrity of the box is maintained during handling.

Another object of the invention is to provide a box ofthe generalcharacter described, in which provision is made for reinforcing thecorners which in boxes made of heavy berboard folded into shape, usuallyhave apertures thru which a product such as a nail readily works.

Another object of the invention is the provision of a box of suchcharacter `that a product like nails may be packed therein at thefactory inV unit lots, such as five, ten or twenty-five pounds, andreach the ultimate consumer without being repackedV into anothercontainer.

Another object of the invention is the provision of a box of thecharacter described made from a fiber-board embodying or faced on theinside with a lining of absorbenit character so that moisturepenetrating the package is retained in the liner without damage to thecontents. i

My invention possesses other objects which with the foregoing will beset forth in the following description of the preferred embodiment ofmeans for practicing the invention, and which is illustrated in thedrawings accompanying and forming part of the specification. It isunderstood that. I do not limit myself to the showing may by the saiddescription and drawings as I may t variations of my preferred form adogwit in the scope of my invention as setl forth in the claim.

It has been the universal custom to pack nails, in the first instance,in kegs which are sold to the jobber and retailed by him either in theoriginal keg, or by the pound in small quantities which the purchasercarries away in a sack. When nails are bought by the keg, the head ofthe keg is knocked in on the job, and the nails used by the workman asrequired. Frequently nails are left over land these are seldom takenaway to a new job, but usually are wasted. In the case of small-sizednails which the workmen freprior to their use, an open keg -collectingdust and dirt means a dirty nail, and with all kinds ofnails, especiallyin wet Weather, delays in using the nails promptly after opening the kegpermit the nails to become rusted which makes them not onlyobjectionable to the workmen but frequently un? suitable foruse. i

It is my purpose to provide a package ofv such size that the exactrequirements of a given job can be more closely approximated andpackages holding vrelatively small quantities of nails openedsuccessively as the work progresses so that always there is a cleanproduct when it is to be used, and prior to use it iis protected fromdeterioration and contamination.

To the ordinary' householder who buys nails in small quantities it isAalways a problem to roperly store the nails until they are used. yackage solves this problem since the houseli) the small quantity whichhe contemplates using, in a relatively small `rectangular package, whicheither alone or in combination with other packages holding dierent sizesof nails, ,fits readily on any availableshelf room. After usin a fewnails the package. may be again c osed thus keeping the contents in goodcondition. By the use of a relatively absorbent liner embodied in thematerial of which my boxes are made, moisture which would otherwise tendto rust the nails is taken into the liner. j

Of late years a heavy yfiber-board has come into wide use in place'oftheformer wooden boxes and to fold this material from a blank sheet it isnecessary to shape the blank, especially around the corners of thecontemplated box, so that the various layers will assume a properrelative position. This is done by'cutting the material away around thecorners and folding the various component panels and flaps on suitablyimpressed crease lines. This common and well-known box structure is notentirely suitable for ackaging such products as nails, a small bul ofwhich are heavy and individual units of which have a wa of working thruthe corners. In the box o my invention I provide a blank of such formthat a portion of the sheet extends over the older may buy his nails incorners closing any aperture and insuring that no nail can protrude. Ialso avail myself of the closure flaps to give rigidity and strength tothe box structure so that it will stand rough handling without damage orloss of contents.

Referring to the drawings:

Figure 1 is a perspective view of the box, a portion being broken awayto disclose the structure.

Fig. 2 is a perspective view of a corner of the box showing the flaps inclosed position.

Fig. 3 is a plan view of ay portion of the blank out of which the box ismade, showing the configuration of the end and side alps at the cornersof the box.

ig. 4 is a sectional view thru the material out of which the box ismade, the plane of section being indicated by the lines 4-4 of Fig. 1.

My box-comprises a sheet of fiberor paper-board divided by suitablyimpressed pairs of crease lines 1 and 2 into side panels 3 and 4; endpanels 6 and 7, end fiaps 8 and 9 on the upper and lower edges of theend panels; and side flaps 11 and 12 on the upper and lower edges of theside panels. Each of the fiaps is integrally connected to its associatedpanel, along a hinge or foldable portion defined by the twin creaselines 1 and the panels are similarly connected by a portion defined bythe twin crease lines 2. When the box is made up the folded edges assumethe appearance indicated by the sectional view, Fig. 4.

The end flaps 8 and 9 are each of the same length as t-he side liaps 11,and in a box of the contemplated proportions, as shown in Fig. l, thispermits a short overlapping of these flaps when the box is formed.

As indicated in Fig. 3 the end flaps on l the side are defined by a line16 starting at the inner crease line 1 separating the iiaps from thepanels, and incontinuation of the outer crease line 2 between the end 6and side 3 and nearest to the end 6. A slot 17 is formed between the endand side flaps which narrows adjacent the hinge lines 1 to a singlesevering cut 18 forming part of the edge 16. In other words the edge 19of the flap 11 is of such form as to provide a tab 21 which may beconsidered to fill the inner end of the slot 17, and when the parts arefolded into box form this tab 21 is found to extend past the corner asindicated in Fig. 2, forming a tight closure at this point and one whicheffectually prevents any nail from working thru the corner to become amenace to everyone handling the box.

I proportion the box in such manner that the flaps 11 are substantiallyas long as the box is wide, so that when the blank is folded, the iaps11 and 12' fold together over the inner end fia-ps 8 and 9, and liesubstantially coincident with each other, each extending oversubstantially the entire width and length-of the box. Since the boxbears on its sides and endsthe desired label referring to contents andmanufacture, the two opposite sides of the'box comprising the foldedfiapswll be the top and bottom in t-he position in which the box isnormally handled and'shipped. Because of the unusual weight of thecontents, the bottoni and tops of the boxes are subjected to thegreatest stress and these as pointed out above comprise threethicknesses of material thruout their extent. The overlapping flaps asdescribed also provide a bracing for the structure which eiiectuallyprevents racking or distortion of the box.

rIhe material out of which such boxes are customarily made iswaterproofed not only because this 'quality is desired but because thewaterproofing very materially increases the strength ofthe material.make the material for my boxes with a chip board foundation 22, having aliner 23, such as leather colored jute, on the outer surface, and aliner 24 of blue jute on the inner surface. The inner liner ismanufactured with less waterproofing material, so that rela-tively, itis somewhat absorbent. The absorbent inner liner will prevent moist-urefrom attacking and adversely affecting the appearance of the nails inthe box. I prefer to use the blue jute liner because of its appearancein connection with the nails. and I find that such a liner verydefinitely increases the salability of the product.

I claim:

A box blank comprising side and flap portion, each flap being integrallyconnected to the associated side along a hinge line formed by parallelspaced creases, adjacent sides being also connected along a hinge lineformed by parallel spaced crea-ses, and two adjacent flaps beingsepa-rated by a slot which narrows adjacent the hinge line between aflap and side to a single severing cut starting at an inner crease lineand in con tinuation of one of the crease lines between the sides.

In testimony whereof, I have hereunto set my hand.
